LuLu, I ended up taking baby aspirin against the advice of my FS...

Brief run down - we know I have existing autoimmune issues, so I demanded testing after my first miscarriage. My FS refused, but I went to another who agreed there were issues to look into. We found I was borderline for having natural killer cell problems, but the medication used to treat it was already being used to treat the existing autoimmune problems. The other FS suggested some changes to my drug dosage and we went back to the original FS. He didn't care about me taking prednisone as it wasn't going to cause issues at all.

Two more miscarriages and my FS finally agreed to look into things a bit further (we never told him about the other testing). This time I came back as being borderline for lupus anticoagulant problems. Problems arise at levels of 1.2 or more, I was sitting on 1.1. My FS assured me it wasn't a problem and we just had to keep trying...

Meanwhile, I'd been seeing an acupuncturist who specialises in infertility, IVF support and miscarriage prevention. Her opinion is that with all of my health issues (I have rheumatoid arthritis and PCOS and a history of chronic fatigue syndrome as well as the NK cells and LAC problems) a level that would be ok for someone else may not necessarily be ok for me, just because there's too much going on in my body and the possibility of different things interacting. Her advice was to take baby aspirin as it is available OTC. She would have preferred me to be on clexane, but there was no way my FS was going to consider it.

So I commenced baby aspirin on the day of my next embryo transfer... At 9 weeks I saw my OB for the first time and she had absolutely no issues with me being on aspirin at all (in fact considered it to be a good idea just with my miscarriage history and no other testing). I carried Sam to almost full term. I was meant to stop the aspirin at 32 weeks, but forgot, and ended up stopping somewhere between 34 and 35 weeks... and gave birth at 36 weeks.

If taking the aspirin would help put your mind at ease, I would honestly suggest doing so, especially if you won't be continuing to see your FS as an OB. Of course, that's just my personal opinion and not based on anything medical at all apart from my own experiences. Sometimes you've just got to follow your gut instinct on what's wrong and how it needs to be fixed... Remember that your doctors may be experts in their field, but they are not necessarily experts on YOU.
